Hey there!
If you message me I can provide you some *watermarked* samples not available in my profile, but roughly, I could do those style illustrations for roughly $300 - $500 per illustration, If you need many I could do a discount.
Anyway, I could start working on this right now, just let me know!
I'm well experienced with both Photoshop and Illustrator,
having worked for many years as an art director in ad agencies
You can see samples of my stuff in my profile
Cheers!
